A preschooler toying with the burners on his mother's stove accidentally sparked New York City's deadliest fire in decades, an inferno that quickly overtook the apartment building and blocked the main escape route, the fire commissioner said Friday.
Four others were fighting for their lives a day after the flames broke out in the century-old building near the Bronx Zoo.
It's the worst fire tragedy in NYC in at least a quarter of a century. The victims killed were seven adults and five children -- ranging in age from 1 to 63.
All people in the building have been accounted for, FDNY officials said.
